The Lowdown

Alright, my friends, Rusty here. Let’s break it down.

It’s been a slow start, but we’ve got some good waves coming in for Jaconé. The first few days are a bit of a mixed bag, but there are a couple of days that are really worth circling on the calendar.

We kick off the weekend with small, clean waves. Saturday morning at Jaconé is seeing a tiny 2ft southerly swell, with a clean 11-second period. The water is sitting at 72°, which is pretty normal for this time of year. The wind is light and offshore from the NE, so it’s glassy. The energy is weak, but it’s rideable. Saturday afternoon swings around to a 3ft easterly swell, but the period drops to 8 seconds, making it a bit choppy and less appealing. Still, the wind is cross-offshore, so it’s clean enough for a shortboard.

Sunday is a washout. Strong onshore winds ruin the 3ft swell, and it’s just messy. Skip it.

Now, Monday 31 August is a solid pick. Morning brings a 6ft swell from the ENE, with an 8-second period. The energy is ramping up and the wind is a clean cross-offshore breeze. The waves will be a bit chunky, but it’s clean and fun. Afternoon drops to 4ft from the east, but still clean. This is a good day for an intermediate surfer.

Tuesday 1 September is back to poor conditions with onshore wind and choppy surf. Not worth a paddle.

Wednesday 2 September gets ugly. A 10ft south-west swell hits with a 6-second period, but it’s blown out by a fresh 22 mph onshore wind. The energy is strong, but the quality is zero. This is more of a kite-surfing setup than a paddle session.

Here’s the standout. Thursday 3 September. Morning sees a 7ft SSW swell with a 9-second period, and the wind is a clean cross-offshore from the ENE. The energy is strong, and the conditions are very clean. This is the best of the run. The swell is a bit big for beginners, but for intermediates and up, it’s a cracker. Afternoon gets a bit windier, but still workable.

Friday 4 September is a sleeper hit. Morning is glassy with a 5ft SSE swell, 10-second period, and light offshore wind from the NE. The energy is moderate and the waves will be clean and fun. Afternoon stays clean with cross-offshore wind. This is a great day for a longboard or a funboard.

The weekend of 5-6 September goes downhill with onshore winds and rain. Poor.

Monday 7 September sees a big 10ft SSW swell with a 10-second period, but again, it’s blown out by strong onshore winds. The energy is massive, but the quality is terrible. Expert only, and even then, it’s a battle.

Second standout – Tuesday 8 September. Morning is a gem. A 8ft S swell with an 11-second period, and the wind is light and offshore from the NE. The energy is strong and the waves will be clean, powerful, and well-shaped. This is for experienced surfers only – the size and period demand respect. Afternoon stays clean with cross-offshore wind, but the swell drops a bit.

Wednesday 9 September keeps the clean run going, with a 5ft S swell and offshore wind. The period is 11 seconds, so there’s plenty of push. Good for intermediates.

The rest of the second week sees the swell dropping, but the wind stays clean. Thursday 10 September has a 3ft S swell with offshore wind, and Friday 11 September has a tiny 3ft ESE swell with offshore wind. It’s small, but clean. Saturday 12 and Sunday 13 September are small and clean, but only knee-high, so it’s more of a glide than a ride.

To sum it up: Thursday 3 September and Tuesday 8 September are the true standouts. Both offer clean, powerful surf with solid energy. The first one is a bit more accessible for intermediates, while the second is for the experienced crew. The water is average temp for this time of year, so no need for a thick wetsuit.

Rusty out.

Information about the Jaconé Surf forecast

The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
